The above claim has a full counterpart with the current law system of most countries, so that the process of document dematerialization has been already started relying on the current infrastructures as well as the current juridical regulations, with strong attention towards common interoperability rules. As a consequence, the issue regarding the vulnerabilities of digital signature is particularly important. This paper presents a new attack to digital signature not based on the insertion of instructions in the document to sign but in the same way producing a non-static visualization of the signed document, with the purpose of producing (legal) effects different from those desired by the signer. The paper proves the attack by example and gives a possible way to contrast it.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121077285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem is becoming more serious considering the exponential growth of the number of Web resources. In the response to these challenges, the meta-search engines are introduced to enhance the search process by devoting some outstanding search engines as their information resources. In recent years, some approaches are proposed to handle the result combination problem which is the fundamental problem in the meta-search environment. In this paper, a new merging/re-ranking method is introduced which uses the characteristics of the Web co-citation graph that is constructed from search engines and returned lists. The information extracted from the co-citation graph, is combined and enriched by the userspsila click-through data as their implicit feedback in an adaptive framework. Experimental results show a noticeable improvement against the basic method as well as some well-known meta-search engines.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122864043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose an incremental maintenance of these horizontal views which updates efficiently them according to the changes of base source tables. We first propose an overall framework processing queries over horizontal views transformed from source tables with vertical form. In order to execute this view maintenance process efficiently, we keep every changes of source tables into differential files then we modify the horizontal views with the differential files. Because differential files have vertical forms, their tuples are converted to horizontal forms which are identical to horizontal views then they are applied to the maintenance of these views. Experimental results show that the proposed method is more effective than existing methods.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132713140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional security mechanism protects data at physical level such as encryption and access control, but todaypsilas organizations need to protect data on both levels physical and logical level. Since the organizationpsilas data may be published and shared by many users. Disclosure is a result of weakness of these security mechanisms. In this paper we discuss the problem of protecting XML data at logical level specifically solve the disclosure problem. The objective is to prevent an unauthorized user to infer sensitive information through the data they authorized to access (result of previous queries), integrity constraints, and using inferences. In most existing access control approaches the XML elements specified by access policies are either accessible or inaccessible according to their sensitivity. However, in some cases, the original XML elements are sensitive and inaccessible, but after being processed in some appropriate ways, the results become insensitive and thus accessible [6]. We propose a security mechanism called Disclosure Prevention Algorithm (DPA) that enhances both the security (by preventing disclosure) and availability (by considering suspected users only) of data represented in XML format.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"60 24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122360298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
